• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu sang) OR (chieu xanh)) - thanh trung ca dang cong ((san than) OR (sang than)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sang) or (chieu xanh)) - thanh trung ca dang cong ((san than) OR (sang than)) cau*".
